California’s Title 24 is the State Building Code. Part 6 of that Code contains the Building Energy Efficiency requirements. The latest version of the Standards has been extensively revised, and is effective as of January 1st 2010. There are many ways to achieve Title 24 compliance. We will show you how to build the building you desire while meeting or exceeding these more restrictive requirements. Please include us in the design process as early as possible. These new regulations are more complex and require more coordination between the various members of the design team. The following list contains a few of the more significant changes.

RESIDENTIAL:

• Upgraded window u-factor requirements.
• Updated lighting requirements, including controls and kitchens.
• Requires mechanical ventilation to maintain indoor air quality, establish standards for ventilation rates, ventilation strategies and modeling.
• Updated swimming pool and spa requirements to include two-speed pumps, time clocks, and limit flow velocity.
• Updated air conditioning refrigerant charge, airflow and protocols; discontinue credit for TXVs.
• New requirements for furnace fan airflow duct design.
• Requires under-slab hot water pipe insulation.

NON-RESIDENTIAL:

• Upgraded insulation requirements for roofs, walls and floors.
• Upgraded indoor lighting requirements.
• Added requirements for high efficacy load shedding ballasts and demand response controls to reduce indoor lighting when signaled.
• Added requirements for occupant sensors in schools and other areas
• Changed the definition of daylit area and requirements for daylighting controls.
• Expanded skylight and daylighting sensor requirements to include smaller buildings and buildings with lower ceilings.
• Updated requirements for lighted signs.
• Changed site-built fenestration requirements.
• Added new requirements for outdoor lighting and building envelopes.
• Expanded direct digital control systems to the zone level.
• Established new envelope and mechanical requirements for refrigerated warehouses.
